Advanced Archive Password Recovery (ARCHPR) recovers protection passwords or unlocks encrypted archives created with popular file compression tools. Guaranteed unlocking of archives created with WinZip 8.0 and earlier in under one hour is possible by exploiting an implementation flaw.


ARCHPR features ultimate compatibility among the various types of archives, knows weaknesses of certain types of protection, and provides best-in-class performance in unlocking all types of archives.


Features and Benefits


Supports all versions of ZIP/PKZip/WinZip, RAR/WinRAR, 7ZIP, as well as ARJ/WinARJ, and ACE/WinACE (1.x)

Guaranteed recovery of archives in under one hour for ZIP archives created with WinZip 8.0 and earlier and containing at least 5 files

Supports archives over 4 GB and self-extracting archives

Supports strong AES encryption found in WinRAR and the new versions of WinZip

Exploits all known vulnerabilities and implementation flaws in the various compression algorithms for faster recovery

Speedy known-plaintext attack recovers certain ZIP and ARJ archives in minutes (user must supply at least one unprotected file from that archive)

Interrupt and resume operation at any time

Supports background operation by utilizing idle CPU cycles

Dictionary and brute-force attacks with user-defined masks and advanced templates

Highly optimized low-level code for optimum performance


Note: the password is not stored anywhere in the archive (ZIP/RAR/ARJ/ACE file), and so it cannot be extracted or decrypted. Instead, ARCHPR can recover it by trying all possible combinations in a given range or a dictionary. While there is no guarantee that the password will be recovered, the human factor plays its role as short and/or easy to remember passwords are the most common.
